Sergio Romero was again in goals during the 1-0 victory over Aston Villa last night as manager Louis van Gaal says De Gea will not be involved until he is '100pc focused' by the end of the transfer window.

Real Madrid are leading the chase to sign the Spaniard, but with only 12 months left on his current deal, may have to wait until next summer if United do not lowe r their €40m valuation.

Either way, De Gea looks destined to leave in the near future and Neville believes the club has to shoulder the blame for the situation they now find themselves in.

"This has been badly managed by Manchester United, make no mistake about that, to allow a player of his quality not to extend a couple of years ago,” he said on Sky Sports.

“He had those couple of dodgy seasons at the start when he was a young, inexperienced goalkeeper adapting to a new country, but under David Moyes he showed real promise.

“The question has to be asked why wasn’t [his contract] extended in that period? To allow his contract to get to this situation is poor management. And now United are paying for it.”

Van Gaal declined to respond to Neville’s remarks and would only say: “De Gea is a question I’ve answered already many, many times, you can read all the interviews and you have my views. I’m not worried.”
